Hi All,

I know the VHT takes a back seat to the NPB for most observers :bow: but I would like to offer this great "mid-band" LPR filter on sale at $50 and $100 (1.25" & 2.0" format respectively). Usual list price is $70 and $140. Sale price includes free shipping to lower 48 states.

For International Orders send inquires to: dgmoptics@erols.com

*** This offer is good only when ordering direct from DGM Optics ***

Basic VHT specs:

Peak TX% = 96-97%
Ave. TX% 486-505nm = 90-92%
Bandwidth = 320nm +/- 2nm
TX% @ 656.3 = 85% minimum
Coating Technology = Ultra-Durable, Ion Assisted Sputtering.
Substrate = Polished Quartz.

And, besides being an excellent astrofilter for smaller scopes, the VHT has also proven to be a very useful CCD filter.

best regards!
